Science Pass Practice

A student attaches a washer to a toy parachute to investigate the relationship between parachute size and falling time. The student drops the parachute from a height of three meters and then repeats the procedure with a parachute of a different size. Each time, the student records the following measurements.

Which tools would provide the most accurate measurements to complete the chart?

• 
•

A student researches changes in the concentrations of greenhouse gases in the atmosphere over the past 2,000 years.

- Forests help absorb CO2.

- Burning and deforestation add CO2 to the atmosphere.

- Agriculture and fossil fuel use result in CH4 production.

- The average lifetime of N2O in the atmosphere is 121 years and of CH4 is 12.4 years.

- The industrial era began around the year 1750.

Which argument about the primary cause for the atmospheric changes is best supported by the evidence?

• The changes are caused by deforestation because it removes trees that absorb CO2.

• The changes are mostly caused by Earth’s current position in the solar system, which is different than it was 2,000 years ago.

• The changes are caused by the long periods of time needed for N2O and CH4 to break down in the atmosphere.

• The changes are mostly caused by industrial activities since those activities began at a similar time as the major changes in greenhouse gas concentrations.

Electrical energy flowing through a circuit is measured in voltage. A teacher measured the voltage at four points on an electrical circuit. Which statement best explains the voltage change as the current moves through the electrical circuit?

• The voltage decrease is due to the chemical energy of the battery transforming into light and heat energy.

• The voltage decrease shows energy being destroyed as the current moves through the electrical circuit.

• The voltage decrease is due to the light energy of the battery transforming into heat and chemical energy.

• The voltage decrease shows energy being created as the current moves through the electrical circuit.
